type sample = {ext : string; | An extension to append to the base metric name. |
value : float; | |
bucket : (LabelName.t * float) option; | The "le" or "quantile" label and value, if any. |
}type t = sample listA collection of values that together represent a single sample. For a counter, each reading is just a single value, but more complex types require multiple values. For example, a "summary" sample set contains "_sum" and "_count" values.
val sample : ?ext:string -> ?bucket:(LabelName.t * float) -> float -> sample
